Description

Technical Field

[0001] This utility model relates to the field of suspended door technology, specifically a braking mechanism for a suspended door. Background Technology

[0002] A suspended gate, also known as a hovering gate, is a gate that moves in mid-air without wheels touching the ground, without running tracks, and without the need for pre-embedded guide rails. Suspended sliding gates are professional intelligent products integrating mechanics, optics, and dynamics. Currently, the known transmission devices for trackless suspended gates are divided into two types: one is an external motor rack and pinion transmission drive device; the other is an internal integrated motor sprocket and chain transmission drive device. Each transmission method has its own advantages and disadvantages, and the choice must be made based on the actual situation. Different transmission methods also require different bottom beam structures.

[0003] In existing technology, the drive wheel assembly is equipped with a braking mechanism, which makes it difficult to manually push the door to slide when the electric switch is not activated. However, the existing braking mechanism is relatively complex and difficult to install. Utility Model Content

[0004] The purpose of this invention is to provide a braking mechanism for a suspended door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a braking mechanism for a suspended door, comprising: a rack fixedly installed on the lower side of one end of the door panel and an electric push rod disposed on one side of the side column assembly 2, wherein the outer end of the electric push rod is provided with a protective shell, the protective shell is fixedly installed on the lower outer wall of the side column assembly 2, and an operating hole is provided on the lower outer wall of the side column assembly 2.

[0006] One end of the electric push rod is fixedly installed on the inner wall of the protective shell, and the other end is fixedly installed with a movable column. One end of the movable column passes through the operating hole and is flexibly connected to a gear.

[0007] The upper end of the rack is meshed with a gear, which is rotatably connected to the inner end of the side column assembly 2 via a fixed rod.

[0008] Preferably, the protective shell is located outside the operating hole.

[0009] Preferably, a guide cylinder is slidably sleeved on the outer wall of the movable column, and a fixing frame is fixedly installed on the outer walls of both the left and right ends of the guide cylinder, with the other end of the fixing frame fixed to the lower outer wall of the second side column group.

[0010] Preferably, a push plate is fixedly installed at the end of the movable column away from the electric push rod. The size of the push plate is smaller than the inner diameter of the operating hole, and a number of sliding holes are evenly opened on the outer wall of the push plate.

[0011] Preferably, each of the sliding holes is slidably connected to a sliding column, one end of which is fixedly installed with a limit plate, and the other end passes through the sliding hole and is fixed to the outer wall of one end of the gear.

[0012] Preferably, a spring is fitted on the outer wall of the sliding column, with one end of the spring fixed to the outer wall of the second gear and the other end fixed to the outer wall of the push plate.

[0013] Preferably, the height of the second gear is higher than that of the first gear, and the outer wall of the second gear can mesh with the outer wall of the first gear.

[0014] Preferably, one end of the fixing rod is rotatably connected via a bearing and a gear. The other end of the fixing rod is fixedly installed on the lower inner wall of the second side column assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By activating the electric push rod, the moving column is moved. The moving column drives the push plate and gear two to move towards the side of gear one. When the teeth of gear one and gear two collide, gear two stops moving forward due to the compression spring, while gear one continues to rotate until the teeth of gear one and gear two interlock. Under the reaction force of the spring, gear two meshes with each other, thus fixing gear one in place. The rack cannot follow the door panel, thus stopping the door panel and completing the braking of the suspended door. This device has a simple structure and is easy to install.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a braking mechanism for a suspended door, comprising: a rack 6 fixedly installed on the lower side of one end of the door panel 3 and an electric push rod 9 disposed on one side of the side column assembly 2. A side column assembly 1 is provided on one side of the side column assembly 2. The door panel 3 passes through the rear shell of the side column assembly 2 and enters the side column assembly 1. A protective shell 5 is provided on the outer end of the electric push rod 9. The protective shell 5 is fixedly installed on the lower outer wall of the side column assembly 2, and an operation hole 4 is opened on the lower outer wall of the side column assembly 2. The protective shell 5 is located outside the operation hole 4. One end of the electric push rod 9 is fixedly connected to the inner wall of the protective shell 5. The protective shell 5 covers the operation hole 4 and supports and protects the electric push rod 9.

[0024] One end of the electric push rod 9 is fixedly installed on the inner wall of the protective shell 5, and the other end is fixedly installed with a movable column 10. The outer wall of the movable column 10 is slidably sleeved with a guide cylinder 11. Fixing brackets 12 are fixedly installed on the outer walls of both the left and right ends of the guide cylinder 11. The other end of the fixing bracket 12 is fixed on the lower outer wall of the side column group 2. The guide cylinder 11 guides and limits the movable column 10. When the electric push rod 9 drives the movable column 10 to move, the movable column 10 slides in the guide cylinder 11.

[0025] One end of the movable column 10 passes through the operating hole 4 and is elastically connected to the gear 17. The end of the movable column 10 away from the electric push rod 9 is fixedly installed with a push plate 13. The size of the push plate 13 is smaller than the inner diameter of the operating hole 4. The push plate 13 can move within the operating hole 4. Several sliding holes 14 are evenly opened on the outer wall of the push plate 13. A sliding column 15 is slidably connected in each sliding hole 14. A limit plate 16 is fixedly installed on one end of the sliding column 15, and the other end passes through the sliding hole 14 and is fixed to the outer wall of one end of the gear 17. A spring 18 is sleeved on the outer wall of the sliding column 15. One end of the spring 18 is fixed to the outer wall of the gear 17, and the other end is fixed to the outer wall of the push plate 13. The gear 17 can move on one side of the push plate 13 by compressing the spring 18. When the electric push rod 9 drives the movable column 10 to move, the movable column 10 moves synchronously with the push plate 13 and the gear 17.

[0026] The upper end of the rack 6 is meshed with a gear 7. The gear 7 is rotatably connected to the inner end of the side column group 2 via a fixed rod 8. One end of the fixed rod 8 is rotatably connected to the gear 7 via a bearing, and the other end of the fixed rod 8 is fixedly installed on the lower inner wall of the side column group 2. When the gate 3 is driven to move by the side column group 2, the gear 7 moves on the rack 6.

[0027] Gear 2 17 is higher than gear 1 7. The outer wall of gear 2 17 can mesh with the outer wall of gear 1 7. When braking is required, the electric push rod 9 is activated to push the moving column 10 to move. The moving column 10 drives the push plate 13 and gear 2 17 to move towards one side of gear 1 7. When the teeth of gear 1 7 and gear 2 17 abut, gear 2 17 stops moving in place due to the compression spring 18. Gear 1 7 continues to rotate until the teeth of gear 1 7 and gear 2 17 interlock. Under the reaction force of spring 18, gear 2 17 meshes with each other, thereby fixing gear 1 7. The rack 6 cannot move with the door panel 3, thus stopping the door panel 3.

[0028] In actual use, when braking is required, the electric push rod 9 is activated to push the moving column 10 to move. The moving column 10 drives the push plate 13 and the second gear 17 to move towards the side of the first gear 7. When the teeth of the first gear 7 and the second gear 17 collide, the second gear 17 stops moving forward due to the compression spring 18, while the first gear 7 continues to rotate until the teeth of the first gear 7 and the second gear 17 interlock. Under the reaction force of the spring 18, the second gear 17 meshes with each other, thus fixing the first gear 7 in place. The rack 6 cannot move with the door panel 3, thus stopping the door panel 3 and completing the braking of the floating door.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
